How to Refill and Reset Brother TN2220 & TN450 Toner Cartridges: Global Guide

By /

Refilling your laser toner cartridges can save you a significant amount of money on office supplies. However, Brother uses different model numbers for the exact same cartridge depending on where you live. In Europe, this cartridge is known as the TN-2220, while in North America, it is the TN-450.

In this guide, we will demonstrate how to maintain these cartridges. Furthermore, we will show you the critical “reset gear” positioning that ensures your printer recognizes the refilled unit, regardless of your region.

Step-by-Step Refill and Reset Instructions

  1. Identify Your Model: First, confirm your cartridge model. Use TN-2220 for European printers and TN-450 for US and Canadian models.
  2. Access the Internals: Remove the side cover screws to reveal the gear system. Consequently, you will see the black plastic reset gear that controls the toner level detection.
  3. Clean the Components: Additionally, you must clean the developer roller and the doctor blade with a lint-free cloth. This prevents streaks and ensures high print quality.
  4. Refill the Powder: Carefully pour the replacement toner into the hopper. However, always leave a small amount of air space to allow the toner to move freely inside.
  5. Set the Reset Gear (The Flag): Finally, position the reset gear in the “new” starting position as shown at. This mechanical “flag” tells the printer that a full cartridge has been installed.
